PREFACE
The Institute for Telecommunication Sciences (ITS) is conducting a series
of projects concerned with the roles of advanced communication satellites in
Integrated Services Digital Networks (ISDN) and the use of advanced satellite
system technology to enhance rapid restoration of services provided by the Public
Switched Network (PSN) following a natural or "manmade" disaster. Goals of this
work are (1) to promote an effective integration of advanced satellite systems
with future terrestrial broadband networks, (2) to perform studies that examine
uses of advanced communication satellite systems to reduce national vulnerability
to telecommunication outages, and (3) to identify and recommend interface and
functional standards required for integrated services, such as ISDN, in a
terrestrial-satellite broadband transmission and switching environment. The
Institute is working with the National Communications System (NCS) and other
Government and industry organizations to define and develop the necessary
standards.
The purpose of the task addressed by this report has been to characterize
separately the terrestrial and satellite networks. It is expected that this
study will provide a foundation for subsequent studies that will explore the
interoperation of terrestrial and satellite networks to reduce national
vulnerabilities to telecommunication outages in case of a broad spectrum of
threats, such as facility damage or traffic congestion.
Certain commercial systems, equipment, and software products are identified
in this report to adequately describe the designs and conduct of research or
experiment. In no case does such identification imply recommendation or
endorsement by the National Telecommunications and Information Administration,
nor does it imply that the material or equipment identified is necessarily the
best available for the purpose.
The views, opinions, and/or findings contained in this report are those of
the author. They do not represent an official position of the National
Telecommunications and Information Administration or of the U.S. Department of

STAND-ALONE TERRESTRIAL AND SATELLITE NETWORKSFOR NATIONWIDE INTEROPERATION OF BROADBAND NETWORKS
Martin Nesenbergs*
The current status of fiber op"tic and related broadbandterrestrial networks is reviewed. That includes summaries of link andswitch capabilities as well as present and future standards forbroadband systems. In the domain of communication satellites, bothexisting and advanced future technologies are described. Advantagesand disadvantages of both terrestrial and satellite stand-alonenetworks are discussed from the service survivability and restoralpoint of view. The presented material is largely technical. As aconsequence, this report does not address such important nontechnicalissues as economics, costs, policies, and the regulatory environment.
Key Words: advanced communications technology satellites (ACTS); fiber optics;satellite networks; terrestrial networks; vulnerability
1. INTRODUCTION
A recent article (Zorpette, 1989) highlights the efforts by the U. S.
telephone companies to maintain nationwide service despite a variety of real
and anticipated emergencies. The article was apparently a direct outgrowth of
the so-called Hinsdale fire. That fire occurred on Sunday, May 8, 1988, at a
major telephone switching center in Hinsdale, IL, a Chicago suburb.
The disaster that followed caused an unprecedented disruption of
telecommunication service. According to the above article, some
35,000 residential and business customers had no service for over a month.
Customers in other areas, served by some 120,000 disabled trunks, had to contend
with no long-distance service. The Hinsdale SWitch, in addition to being a
local central office, also served as an interexchange gateway hub, or a point
of presence (POP), for all three maj or U. S. interexchange carriers: AT&T
Communications, MCI Communications, and U.S. Sprint. Normally, Hinsdale
concentrated and handled up to 3.5 million telephone calls per day. The
accident removed this capability from the Public Switched Telephone Networks
(PSTN), as well as from all attending private networks.
*The author is with the Institute for Telecommunication Sciences, NationalTelecommunications and Information Administration, U.S. Department of Commerce,Boulder, CO 80303.
The effect on end users was severe. O'Hare's air-traffic control, managed
by FAA communications, came to a standstill and the airport had to operate at
a very reduced level. Emergency 911 service disappeared, as did the regional
cellular telephone service. Many businesses, from automatic teller machines,
to stockbrokers, to point-of-sales terminals, and so on, had to cease
operations. Total dollar estimates of lost business ranged from hundreds of
millions to tens of billions.
Yet, as unlikely an event as a switching center fire may be, it is
nevertheless just one of many perils that the nationwide network can encounter.
The quoted article (Zorpette, 1989) illustrates some dozen man-made and natural
causes that can have catastrophic consequences on the terrestrial network:
Battery leaks in central offices can damage and disable equipment.
Construction activity (i.e., backhoes) can sever optical fiber trunks.
Earthquakes can demolish central offices and sever trunk lines.
Fires in nearby industries (i.e., factories) can spread to centraloffices.
Flooding can interrupt power to central offices.
Hurricanes can topple satellite dishes, disabling transoceanic links.
Marine activities (i.e., dredging, trolling) can damage transoceanicunderwater trunks.
Terrorist bombs at signal transfer points can knock out call-routingand nationwide data bases.
Tornados can destroy most structures, especially microwave towers andrepeaters.
Truck accidents can release corrosive gases that interfere withcentral office equipment.
Vandals can destroy microwave towers and do harm to manhole'repeaters.
The above list, while relatively detailed, is nevertheless mainly focused
on terrestrial hardware disasters. Recent events have shown that there exist
new significant threats in terms of network software vulnerabilities (National
Research Council, 1989). Several factors contribute to this vulnerability.
2
First, the modern networks have become increasingly dependent on software
for control, signaling, and various administration, operation, and maintenance
(AO&M) functions. Second, the Federal Communications Commission (FCC) has
mandated that the Regional Bell Operating Companies (RBOC' s) provide Open
Network Architecture (ONA) access to nonnetwork-based service providers. Third,
new network services are being introduced at a rapid pace, and many of them
require user access to different parts of the software. Finally, there are the
huge, centralized, computer-accessed data bases that serve the national and/or
international information services (e.g., call answering, 800 services,
electronic fund transfer, credit card verification, and broadcast news service).
Up to now, the threats to network software have corne mainly from "hackers."
(A notable exception was the recent penetration of the data base at the Lawrence
Livermore Laboratory by foreign agents from West Germany.) Unfortunately, these
hackers are becoming more numerous and more sophisticated as time passes. Their
penetration and manipulation of software has created a family of such, more or
less harmful, symptomatic terms as "viruses," "worms," and "time bombs." If
unauthorized access is achieved by "hostile hackers," serious damage can be done
to both stored information and executable codes. The consequences could be
quite extensive. Large parts of the network could be disabled. Correspondingly
large sectors of the user population could lose essential services, perhaps
exceeding the losses caused by the hardware disasters listed earlier.
Another category of threats to network survivability is associated with
military activities and events. Isolated events, such as the Cuban missile
crisis or the invasion of Grenada, give rise to traffic congestion that may
degrade the service by blocking certain call requests or by delaying others.
More extensive wars can cause far more damage and service disruptions. A
particularly disruptive example can be found in various high-altitude
electromagnetic pulse (HEMP) effects on the software stored in integrated
circuitry, such as VLSI.
Service can also be degraded on a completely undamaged network by traffic
surges that exceed the design (also called the engineered load) levels. Caused
by predictable events (e.g., Christmas or Mother's Day) or some totally
unpredictable events (natural or man-made), traffic congestions can take
considerable time to clear and to return the service to normal quality.
3
Faced with all the above threats to the survivability of the terrestrial
public networks and their services, one is obliged to seek practical
alternatives to reduce the risks to end-user services. There may be many
potential solutions, such as extensive physical hardening and protection of
exiting terrestrial facilities; addition of multihoming terrestrial lines and
trunks, perhaps emphasizing lightwave (fiber optic) technologies; and
introduction of additional nonterrestrial backup connectivity when and where
such backup is needed.
It seems evident that satellite backup facilities can offer beneficial
means for service outage prevention and, when outages occur, for accelerated
disaster, recovery. It is also clear that there are many complex alternatives
for implementing such satellite backups. The resultant advantages and
disadvantages, or recovery speed and capacity versus cost, can only be
ascertained from an in-depth study of various realistic backup alternatives.
First, however, it is necessary to identify and to characterize the main objects
of the study--the terrestrial networks (present and future) and their
counterparts, the present-day communications satellite networks.
The material of this report is organized as follows. Section 2 reviews the
terrestrial networks, with emphasis on broadband facilities, such as the present
and future fiber optics. Links, switches, and standardization issues are
described. The relative advantages and disadvantages of the terrestrial plant
are briefly summarized from the service survivability point of view.
Section 3 looks at the current status and future proj ections for the
satellite communications technology. Again, the section concludes with a
condensed survivability summary, that is, the relative advantages versus
disadvantages of the U.S. communication satellite networks.
Section 4 is a brief conclusion, while Section 5 presents a list of
references.
2. CURRENT STATUS OF FIBER OPTIC AND RELATED BROADBAND TERRESTRIAL NETWORKS
A.network is typically represented as consisting of two major components:
the links (also called channels, transmission paths, trunks, or lines) and the
nodes (different types of switches, central offices, or exchanges). These
components possess numerous distinctive and often complex hardware, software,
4
1·
and functional characteristics. The existing stand-alone terrestrial networks
are no exception. Their links, switching nodes, and other facilities have
experiences a dramatic recent growth. The current status of these terrestrial
network components is described in the next subsections.
2.1 Large Capacity Links
Following the Bell System divestiture of January 1, 1984, the U. S.
telecorr~unications networks of AT&T, BOC's, independents, and other long
distance carriers have continued to evolve. All together they constitute a
large public and private investment in communications. Thus, while exact or
constant numbers are hard to pin down, it is claimed that in the mideighties
there were in excess of 20,000 switching offices and more than 1 billion miles
of transmission paths interconnecting the switches (Falconer and Powers, 1983).
A typical physical path carries more than a single voice frequency trunk. Thus,
there are estimates of over six million telephony trunks and about the same
number of special service, digital and analog, circuits. Almost a 100 million
customer loops terminate at the switches. Between 70 and 80 percent of the
total traffic is believed to be voice today. The network is engineered to
handle more than 1/2 billion, and perhaps as high as 1 billion, calls every day.
Both in terms of equivalent Erlangs or the link bandwidth occupied, data
traffic constitutes an ever increasing portion of the total offered traffic.
In 1983, the relative data traffic volume was estimated to be close to
10 percent (Pagones and Reilly, 1983). By 1990 the data volume should exceed
30 percent.
The Digital Data System (DDS) was established in the midseventies. It
provided public and private data service, called the Dataphone Digital Service
(also DDS). The DDS data rates ranged from 2.4 to 56 kb/s, which was a
substantial improvement over the previous 300 and 1200 b/s rates. Over the last
15 years, such data services have been multiplexed together with digitized voice
in groups of 64 kb/s (DS-O) channels on the so-called T-carrier. The 56 kb/s
service has been customarily carried on 64 kb/s channels. The difference of
8 kb/s has been useful for in-band signaling (e.g., on-hook/off-hook
indication), framing, and related functions. The T-carrier has been widely
transmitted over commercial analog microwave radio systems, such as the 4-GHz
5
system called TD and 6-GHz systems called TH and AR6A. In addition to voice and
data, television broadcasts and other special services have also been
transmitted by microwave radio. Twenty-four DS-O channels constitute one DS-l,
also known as the 1.544 Mb/s Tl line.
More than 10 years ago, customer requirements and economics indicated a
need for much higher rates. The microwave radio industry response has been
threefold. First, around 1980, there was the introduction of several digital
radio systems such as the DR 6-30 at 6 GHz and the DR 11-40 at 11 GHz. Second,
the digital rate hierarchy for radio has been extended far above Tl to
6.312 Mb/s (DS-2), 44.736 Mb/s (DS-3), and to several multiples thereof. And
third, the service offering's have been extended past DDS to what were for a time
called the High-Speed Switched Digital Service (HSSDS) and the High-Capacity
Digital Transport Service (HCDTS). In addition to microwave, these systems
employed satellite links. To emphasize the distinctions, the terrestrial HSSDS
has been renamed the ACUNET Tl.5 Service. The satellite HSSDS has been renamed
the SKYNET 1.5 Service. As the names imply, these transmissions are carried on
dedicated or reserved 1.544 Mb/s Tl lines. Voice, data, and video are
transmitted between switching nodes.
The microwave repeater spacings vary, depending on terrain and related
parameters. For DR 6-30 the spacings are betweeIl 20 and 35 miles; for DR 11-40,
between 10 and 20 miles. Figure 1 shows the main transmission routes of the
Bell System long distance network around 1980. The majority of these links can
be assumed to have been microwave radio.
The modern digital microwave radio systems emphasize spectral efficiency
by using such sophisticated tools as high-level Quadrature Amplitude Modulation
(QAM) , space and/or frequency diversity combining, transversal or decision
feedback equalization, cross-polarization interference cancellation,
predistortion- type linearizing, phase jitter recovery techniques, and
forward-acting error correction (FEC) (Noguchi et al., 1986; Hart and Steinkamp,
1987; Meyers and Prabhu, 1987; Kohiyama and Kurita, 1987). The objective is to
achieve a bit error rate (BER) of better than 10-10 in normal operation. Table 1
shows candidate systems from Europe and North America. Their typical channel
bandwidths are either 20, 30, or 40 MHz. As decreed by FCC, the allowed data
rates in North America would go from two DS-3's (roughly 90 Mb/s) to six DS-3's

** FCC requires a minimum of78 Mb/s for common carriers
(270 Mb/s). To achieve the highest rates, the radios require N-ary modulations,
denoted as N-QAM in the table, with N as hi~l as 256 and even 1024.
To bring compatibility to the growing family of transmission rates both
domestically and internationally, leading standards organizations such as the
American National Standards Institute (ANSI) and the International Telegraph and
Telephone Consultative Committee (CCITT) are introducing new and far-reaching
standards for broadband networking. More about these present and £uture
standards will be said in Section 2.3.
Before the advent of fiber optics, the only competition to microwave radio
came from mu1tiwire and coaxial cables. Neither was a maj or threat. The
twisted wire pairs have their well known bmldwidth/distance limitations. The
coaxial cable, while capable of data rates well above 100 Mb/s (as seen in CATV
systems), has economic drawbacks for long-haul applications.
Optic Fibers
Terrestrial systems took a large forward step in 1977, when the first fu11
service fiber optic system was demonstrated in Chicago. Called a "lightwave
system" by AT&T, it combined voice, data, and video transmissions. In the
intervening dozen years, many optic fiber systems have been installed and put
to various short- and long-distance uses (Jacobs, 1986). Today glass fibers
are replacing terrestrial and satellite microwave, coaxial cables, and
twisted-pair copper wires in almost all kinds of transmission link
installations. That includes the interexchange or long-haui network, the·
exchange network between intra-LATA switches, feeder lines to remote terminals,
as well as to a lesser extent, local loops to individual offices and residences.
Trade literature reports that the United States currently has more than
2 million miles of optic fiber (Kaiser et al., 1987), which would be less than
1 percent of the total trunk mileage. Yet, that small fiber percentage is
alleged to have more than doubled the capacity of the entire Public Switched
Telephone Network (PSTN). Figure 2 shows a 1987 version of the nationwide fiber
optic network in the continental United States. It consists of 11 long distance
carriers, such as AT&T Communications, MCI, U.S. Sprint, etc., and the 8-member
National Telecommunication Network Group (NTN). The fiber optic networks
installed over the last decade have developed interconnect rules that are
particular to different parts of the world. Thus, Table 2 summarizes the main

data rate differences between North America, Europe, and Japan. These rates are
not identical with those for microwave radio (compare Tables 1 and 2).
Multiplexing and switching of long-haul optic trunks take place at standard
digital cross-connects (DSX). In the United States,-Level 3 cross-connects are
called DSX-3. They employ the DS-3 rate (44.736 Mb/s), and their deployment is
common. Europeans prefer cross-connection at their CEPT-4 level (139.264 Mb/s),
while networks in Japan cross-connect at DSX-5 (397.20 Mb/s).
The initial fiber optic linkage of the U.s. mainland with Europe and Asia
was achieved by 1988 (Higdon et al., 1986; Cochrane and Brain, 1988~ Trlschitta
and Chen, 1989). The current status of the major transoceanic systems is
summarized in Table 3 (Elliott, 1989). The first operational transatlantic
system is called TAT-8. The first transpacific linkage joins HAW-4 and TPC-3
in Hawaii. Both employ single-mode fiber optic cables and promise a data rate
in thousands of DS-O or their equivalent channels. Other more advanced systems
are being planned, as indicated in the table.
The widespread use of fiber optics ~S, of course, due to their
extraordinarily high bandwidth plus associated economic benefits (Rogalski,
1987). A single-mode fiber with a repeater spacing of 30 km or less is said to
have a potential terahertz bandwidth (Li and Linke, 1988; Acampora et al.,
1987) . Realistic fibers sell for around $200 per km if purchased in large
quantities. Typical installation and terminal costs are a fraction of the fiber
costs. The expected lifetime of the optical fiber is 30 years, which should
allow for significant future technology upgrades of terminal facilities. The
currently available terminal devices, such as single-mode lasers, semiconductor
light-emitting diodes, semiconductor optical amplifiers, various _ detectors,
modulators, demodulators, etc., are already quite efficient and affordable
(Dixon and Dutta, 1987; Gartside et al., 1987; Kalish and Cohen, 1987). A new
system called LAMBDANET (AT&T TM) is said to use 18 Wavelength Division
Multiplex (WDM) channels of 1.5 Gb/s each (Wagner and Kobrinski, 1989). Its
total data rate of 27 Gb/s is based on repeater spacing in excess of over 55 km.
Reported research studies indicate that further advancements can be anttcipated

2.2 Switch Capabilities
Prior to divestiture and essentially just before the #5ESS made its entry
into the market, the U.S. PSTN was dominated by three generic types of switching
machines. They were different versions of the step-by-step (SXS) , the crossbar
(XBAR) , and the Electronic Switching Systems (ESS) (Joel, 1982). At that time
the biggest workhorses were the SXS switches. As Table 4 shows (Nesenbergs and
McManamon, 1983), the SXS family made up 63 percent of the total switch count
and served 47 percent of all the lines and trunks. One can surmise that the
step-by-steps must have then carried nearly half of the total PSTN traffic.
Except for the #4ESS (the large toll switch) and the soon-to-appear #5ESS
(the adaptable local switch), the exchanges of that era were all analog circuit
switches. As such, they were poorly tailored to serve the future network
requirements in benign and hostile environments (NCS, 1988). Driven by new
technologies, service needs, and general market evolution, the then existing
switching networks were in effect forced to modernize (Malek, 1988) by
implementing such features as equal access requirements, new network
architectures, new common-channel signaling systems, integration of digital
switching and transmission, and dynamically rearrangeable private networks, as
well as integration of voice, data, and other services. Next we comment briefly
on these relatively new developments.
Equal Access
An individual user terminal, typically a telephone that receives either
public or private network service, homes either on a local switch (also called
the end office or EO) or on a private branch exchange (PBX). The EO usually
belongs to the local telephone company. The PBX: is either privately owned or
shared between private networks. At the same time, the long-haul connectivity
in the United States is offered by several interexchange carriers, such as AT&T
Communications, MCI, U.S. Sprint, and so on. To enhance competition, a number
of equal access rules and regulations have been implemented by the FCC and the
Judiciary. The local switches are required to provide access to the so called
Points 'of Presence of the long-haul carriers (if such exist locally). A uniform
Nationwide Numbering Plan (NNP) is needed for the equal access to work
effectively. A tariffed access fee is charged by the local telephone company
for the additional access facilities, their usage, and related expenses. In the

future, equal access to enhanced services is planned by means of the Open
Network Architecture (aNA).
Network Architecture
Prior to 1984, the Bell System's long-distance network had a rigid
hierarchical architecture. Thus the switches or offices were classified as
either Class 1, 2, 3, 4, or 5. At the same time, the first four classes were
denoted as Regional, Sectional, Primary, and Toll Centers, or Points,
respectively. The Class 5 consisted of local EO's and local tandem swi~ches.
The hierarchy defined fixed routing, including alternative routing, rules for
the network. These rules were far from optimal when faced with the new
integrated traffic demands. In the mideighties, a new two-level architecture
was introduced (Cummings et al., 1987). The more advanced switches, such as
mostly those from Classes 1 to 4, were combined into a single class that
possesses the Dynamic Nonhierarchical Routing (DNHR) capability. The remainder,
typically Class 5 EO's, stayed essentially unchanged and without the benefit of
DNHR. DNHR relies on a separate high-speed signaling network to select routes
for calls and messages. Only after the route has been selected and the
terminals have been found not busy, is the connecting path switched through the
interexchange network. To indicate the possible nature of future network
architectures, Figure 3 illustrates a projection of the AT&T network for 1995.
Note that in this concept, PRI stands for the primary ISDN channel (23B+D or
1. 5 Mb/s). The EO's are part of Local Access Transport Areas (LATA), while
private networks are allowed to be either inside or outside the AT&T switched
network. The following additional acronyms are used:
CCS - Common Channel Signaling
CPE - Customer Premises Equipment
EPSCS - Enhanced Private Switched Communicati.ons Service
ESC - Enhanced Service Complex
lAD - Integrated Access Distributor
ISDN - Integrated Services Digital Network
SDN' - Software Defined Network.

Signaling
Interoffice signaling has received considerable attention and major
upgrades in the eighties. The basic developments started with the Common
Channel Signaling (CCS) systems, where separate networks were assigned to carry,
in common, control information for many circuit paths (or message transactions)
on the interexchange network (Lawser and Oxley, 1987). AT&T has historically
called their CCS version Common Channel Interoffice Signaling (CCIS). Either
way, CCS or CCIS is essential for DNHR in the new two-level network
architecture, the real-time management of private networks, and many of the
service functions and features envisioned today. Separate CCS nodes, called the
Signal Transfer Points (STP) , receive, process, and distribute signaling
messages that control the network. A few years ago there were 20 STP's in the
United States, augmented by their dedicated CCS Network Control Point (NCP) and
its associated data bases (DB). Of course, not all existing switches can
benefit equally from the CCS networks. The older analog switches need upgrades,
such as signal converters, buffers, and CPU's, t:o interact with CCS. It is the
more recently introduced digital switches that benefit most. In the meanwhile,
the signaling systems are themselves being improved. The domestic CCIS format,
as well as the internationally more accepted Signaling System #6, are both
gradually being supplanted by the new CCITT System #7. The key feature of
System #7 seems to be its discretionary, user-assigned data field.
Integration of Digital Switching and Transmission
Today, many small and large digital (Time Division Multiplex or TOM)
switches continue to be installed. Prominent among the existing systems may be
the #5ESS of AT&T (Carney and Prell, 1986), but other machines, such as the GTD
5EAX of GTE, the DMS 100 of Northern Telecom, the NEAX 6lE of NEC, the Siemens
EWSD, and others, are also quite advanced digital circuit switchers and as such
occupy a significant part of the U. S. market. Crucial elements of the TDM
technology are the Time Slot Interchangers (TSI), the processor units (CPU),
memories, high-speed data busses, and a general modular (expandable and
remotable) structure (McDonald, 1983). Given line and trunk cards for format
conversion, such digital switches can be extremely compatible with digital
18
transmission media, be they T-carrier microwave or any of the broadband fiber
.rates. That should enable a heretofore unrealized efficient integration of
digital transmission and switching functions (Hui, 1989). However, to be fully
effective at the foreseen high data rates, such digital integration is seen to
require the same switching fabric to handle all varieties of offered traffic.
The definition of this relatively new term, "switching fabric, II is approximately
the following. The fabric refers to the architecture of the switch; with added
emphasis on the broadband structure of the switching matrix and associated
transport functions. While specific choices have not been put into practice,
a considerable amount of current research and development work is said to be
devoted to finding the right fabric.
Adaptive Private Networks
A substantial fraction of interexchange carrier business is due to private
networks. Long known by various names, such as Common Control Switching
Arrangements (CCSA), Inward and Outward Wide Area Telecommunications Service
(WATS), Switched Service Networks (SSN), Enhanced Private Switched Communication
Service (EPSCS), plus others, they used to and still do provide telephone
service to certain permanent user communities over fixed private lines. Now all
that has undergone changes. Not only are there more new services, for instance,
circuit switched and packet data, secure digitized voice, facsimile, facility
restriction (e. g., elimination of specific radio or satellite hops, call
screening, preemptive priorities), but the clients now may demand almost
instantaneous reconfiguration of the entire network topology. This network
service has been made available to the public by the relatively recent,
tariffed, offering of the Software Defined Network (SDN). The topology and
other characteristics of each SDN are stored in the SDN data base. Under
instructions from an appropriate Network Control Center (NCC) , the structure of
the network can be modified at any time. Individual calls are processed by
reference to the stored configuration. The SDN concept relies heavily on such
modern switched network characteristics as CCS, DNHR, and the general
coordination of digital facilities.
19
Integration of Voice. Data. and Other Services
Integration of telecommunication services at standardized user-network
interfaces would obviate the need for dedicated (perhaps separate) facilities
to transport arbitrary end-to-end transactions over different public and private
networks (Chen and Messerschmitt, 1988; Habara, 1988). Unfortunately, however,
the existing and especially the older network facilities are neither compatible
nor adaptive when faced with an arbitrary mix of voice, data, and other
services. Transmission lines may be optimized for certain transmissions.
Likewise, swi tches are des igned for a single service or, at mos t, for a
specified traffic class (circuit switched voice, circuit switched data, message
switched data, packet switched data, etc.). To handle all the services at once,
in the existing type of networks, would require a number of specialized switches
and subnetworks in parallel. Yet the goal of service integration seems worth
pursuing. A large number of organizations have been actively researching the
switching needs for the Integrated Services Digital Network (ISDN) concept
(Anderson, 1987; Spears, 1987; Perucca et a1., 1987; Malek, 1988). To date,
definition and standardization work on ISDN has produced many results. More on
ISDN and broadband ISDN will be discussed in Section 2.3.
2.3 Standards for Advanced Broadband Systems
The advancing technologies of broadband transmission and switching have
created a real need for system interoperation and standardization. Like the
technologies, standards also continue to evolve (Boehm et al., 1986). In the
United States, the basis for standards activities is found in three
organizations: the Electronics Industry Association (EIA) , the Institute of
Electrical and Electronics Engineers (IEEE), and the Exchange Carriers Standards
Association (ECSA). Jointly, they sponsor the U.S. Standards Committee Tl,
which is concerned with telecommunications and proposes (i.e., drafts)
telecommunication standards. All of the above groups are accredited by the
American National Standards Institute (ANSI), which reviews their proposals.
If a proposed standard is approved by ANSI, it becomes an American National
Standard.
The actual work of Tl is done by its six technical subcommittees. The
subcommittee names and areas of responsibility are

TlYl Special Subjects
The topics of TlSl and TlXl appear to be most pertinent here.
International standards for terrestrial networks are developed by the
International Telegraph and Telephone Consultative Committee for (CCITT).
Committee Tl cooperates with U.S. CCITT representatives, such as those of Study
Group C, to support the U.S. position on various issues. The work of the CCITT
is performed by its own respective Study or Working Groups. Study Group XVIII
deals with digital networks.
OSI
The CCITT, the International Standards Organization (ISO), and U.S.
organizations concerned with standards, have for over 10 years now accepted the
seven-layer Reference Model for Open System Interconnection (OSI). The OSI
standard model simply forms the basis for most of the current and future
advanced digital network standards being developed today. The application of
the OSI model to analog (i.e., voice frequency) networks has been attempted, but
with little or no reported success. It appears safe to say that OSI does not
apply to analog networks. Figure 4 depicts the familiar OSI model (Tanenbaum,
1981). Starting with Layers 1, 2, 3, ... , a lot of work has gone in definition
and standardization of the interfaces involved.
From the broadband network point of view, the three lowest layers that fall
inside the communication subnet boundary of Figure 4 are of most significance.
Those are the network-specific Physical Layer (#1), the Data Link Layer (#2),
and the Network Layer (#3) itself. They all must have standard interlayer
protocols, as well as pier protocols, that extend on the same level across all
relevant network interfaces. Of most importance to this report seems to be the
data rate hierarchies of broadband channels. They belong in Layer 1.
As an illustration of the role that OSI plays in standardization, consider
the D channel protocols needed for ISDN (Roca, 1986).

services and can be ignored in this network study.
ISDN and BISDN
In 1984, CCITT issued several Recommendations that defined the standard
general-purpose interfaces of the Integrated Services Digital Network (ISDN).
The intent of the first definitions was to concentrate on 64 kb/s channels.
Today, that would be called narrowband ISDN or just ISDN (Roca, 1986;
A1dermeshian, 1986; Higdon et al., 1986). In addition to digitized voice, the
allowed services include circuit switched data, X.25 packets, facsimile,
videotext, limited-motion video, and versions of voice/data integration. The
standard ISDN interface, also called the Basic Access or Basic Rate Interface
(BRI) , is defined as a combination of two 64 kb/s Bearer (B) channels plus a
16 or 64 kb/s Data (D) channel. For a more complete listing of ISDN channel
rates see Table 5. Note the Primary Rate Interface (PRI) that has a 23B+D
structure, adding up to a Tl rate of 1.544 Mb/s. The High-Speed (H) hierarchy
extends upward from HO, which is 6B or 384 kb/s. The H rates are multiples of
HO. The Band H channels are transparent to the user. They are said to have
Glear Ghanne1 Gapabi1ity (GGG). The D channel is not GGG, as it must carry
network signaling information (Roca, 1986).
The standard user/network interfaces of ISDN are indicated in Figure 5.
There are four interfaces denoted alphabetically as R, S, T, and U. Interface
U joins the network channel termination equipment, identified as Network
Termination NT1, to the transmission line (perhaps 2B+D) that serves the ISDN
switch. It is of most concern to the switched interexchange network.
Interface T is between NTl and NT2, where the latter could be the PBX trunk side

or a terminal controller. Interface S connects NT2 to either of several ISDN
standard Terminal Equipments, TE or TEl, or to a Terminal Adaptor (TA). The TA
is needed to provide ISDN services to non-ISDN Terminal Equipment (TE2).
As indicated in Figure 6, the ISDN switch needs four maj or functional
elements that mayor may not be separate physically. The four switch elements
are a circuit switch, a channel switch, a packet switch, and a signaling switch
(Minzer and Spears, 1989). On the network side these subswitches interface
respectively with any number of circuit-switched subnetworks, private-line
subnetworks, packet-switched subnetworks, and at least one signaling subnetwork
with a dominant role for Signaling System #7. On the terminal side the switch
faces the routing and sign'aling units. The routing unit interfaces with the
Network Termination 1 (NT1) ,which performs all OSI Layer 1 functions. The
dashed lines in this figure indicate the D channels. The solid lines denote the
B or higher-rate H channels.
As seen from Table 5, the ISDN hierarchy allows for numerous high- rate
channels. It has been noted in recent years that there is an increasing network
trend toward the higher rates (Kraimeche and Schwartz, 1987). This activity,
caused in part by optical fiber requirements, has long exceeded 100 Mb/s. Such
capacities would accommodate the integration of all previous services plus such
wideband signals as digital full-motion video. To distinguish it from the old
ISDN, the expanded bandwidth network is called the Broadband ISDN (BISDN)
(Haendel, 1989; Byrne et al., 1989). The BISDN systems are planned for joint,
asynchronous and synchronous, multiplexing and switching functions. The
Asynchronous Time Division (ATD) is performed in the Asynchronous Transfer Mode
(ATM) , which can be considered as an additional OSI Layer that straddles the top
of Layer #1 and the bottom of Layer #2 (Haendel, 1989; Gechter and O'Reilly,
1989; Rider, 1989). ATM is responsible for bit transmission, as well as for
packaging of bits into fixed size "cells," and appending them with labels and
headers. In the ATM, cells are filled according to actual demand. That causes
cells of a particular message exchange to exhibit an irregular arrival pattern.
Channel rates for ATM are expected to be in the H2 to H4 range. The Synchronous
Transfer Mode (STM) may be taken as sequentially filling all cells. It implies
a circuit-switched operation, quite analogous to existing PSTN and narrowband

by displacing STM as the main mode of the BISDN future.
SONET
The acronym SONET stands for Synchronous Optical Network. More
significantly, it represents the newly adopted ANSI, CEPT, and CCITT standard
for optical network interfaces (Boehm et al., 1986; Kaiser et al., 1987; Ballart
and Ching, 1989). The SONET meets four key objectives:
Because of the ever-increasing optical channel bit rates, ~as from100 to 1000 Mb/s and up, it provides a family of standard digitalinterfaces appropriate for these high rates.
• To accommodate the common DS-3 format of 44.736 Mb/s, SONET ratehierarchy is constructed on a base rate near 50 Mb/s.
Since the current tendency of digital networks is a drift fromasynchronous to p1esiosynchronous, to synchronous operation, the SONETis intrinsically synchronous (e.g., in its internal multiplex), andyet it must be capable of working in a p1esiosynchronous environment.
Sufficient overhead capacity must be allocated for future controlsplus Administration, Operations, and Maintenance (AO&M) functions.
Synchronization will be controlled by a Reference Frequency (RF) , which in
turn will be derived from several atomic clocks strategically located in the
United States. The RF will keep SONET in phase, eliminating the need for bit
stuffing and related complications. The necessary hardware and software for
SONET facilities should appear by the 1990's.
The basic building block of the SONET rate hierarchy is called, at least
in the United States, the Synchronous Transport Signal--Level 1 (STS-1). The
line or Optical Carrier (OC) rate of STS-1 is 51.84 Mb/s. That rate is realized
by repeating 8,000 times per second the STS-1 frame that consists of 9x90=810
8-bit bytes. The structure of the STS-1 frame is illustrated in Figure 7. Note
that 27/810=1/30 of the total capacity is assigned to SONET Section and Line
Overhead functions, definitions and details of which are still being studied.
That leaves 783 bytes per frame for the Synchronous Payload Envelope (SPE). The
SPE is further divided into 9 bytes for Path Layer Overhead and the remaining
774 bytes for actual clear channel capable (CCC) SONET payload. Observe that
the 8,OOO-Hz frame rate agrees with DS format used here and abroad.

From the previous discussion (and other sources) it is evident that
stand-alone terrestrial networks possess numerous characteristics and tradeoffs.
In this 'section these traCleoffs are summarized in two parallel columns as
"advantages versus disadvantages." To introduce some order in the procedure,
the tradeoffs are grouped under specific network attributes, such as Topological
Coverage, Traffic Capacity, and so forth.

A great variety of traffic(i.e., service) mixes are routinelymanaged under normal circumstances.
The facilities have beenengineered to operate duringforecasted busy hours at nearly fullcapacity. The networks therefore arequite efficient and competitive.
The overloads typically degradethe end-user GaS, sometimes limitingtheir service a~cess for extendedperiods of time.

The Fa channel performance, suchas BER, is quite good.
Fiber cables are easy to handle,compac t , immune to EMI, and ruggedenough for even the harshest ofenvironments.

3. CURRENT STATUS OF SATELLITE COMMUNICATIONS
In 1963, Syncom II was the initial communications satellite placed into a
synchronous or Geostationary Orbit (GSO). Two years later, it was followed by
the Early Bird, also known as INTELSAT I. Since that time, numerous other
Intelsat, U.S. domestic, and international communication satellites have been
launched. With relatively few exceptions, the majority of them are GSO.
3.1 Communications Satellite Technology
The launches, orbit assignments (equatorial E-W longitudes), and operations
of the GSO satellites follow worldwide policies and regulations set by the
International Telecommunication Union (ITU) , or more specifically, by its
subordinate International Radio Consultative Committee (CCIR) and the
International Frequency Registration Board (IFRB). In the United States, the
international coordination with IFRB, as well as the domestic authorizations and
operational rules, are set by the FCC.
In this section, the emphasis is on U.S. domestic communications satellites.
Being of the GSO type, the service provided by these satellites to fixed earth
stations is also known as the Fixed Satellite Service (FSS).
Of course, not all satellite service is ordinary communications. We next
briefly summarize all alleged U. S. satellites, followed by a more thorough review
of the U.S. communication satellites.
Military
The U.S. Air Force Satellite Communications (AFSATCOM) system.
The Defense Meteorological Satellite Program (DMSP).
The Defense Satellite Communications System (DSCS), especially the DSCS II
and III series of satellites.
35
The Fleet Satellite Communications (FLTSATCOM) system.
A satellite service called LEASAT, which is a Hughes CQmmunications Service
leased by the U.S. Army, Navy, and the Air Force.
The MILSTAR satellites.
The North Atlantic Treaty Organization (NATO) operates a multi-satellite
GSO system, currently in its third or fourth generation.
The Satellite Communications (SATCOM) series. The SATCOM II system is the
planned U.S. Navy replacement for FLTSATCOM and LEASAT systems.
Other Strategic Satellite Systems (SSS), such as those constituting the
third phase of AFSATCOM.
Mobile
The International Maritime Satellite Organization (INMARSAT) provides
maritime, ship-to-ship and ship-to-shore, mobile satellite services. The system
leases space segments from INTELSAT, COMSAT, and the European Space Agency (ESA).
Maritime Satellite (MARISAT) system was a precursor to the INMARSAT, as well
as an early support for the FLTSATCOM system.
Certain INTELSAT V satellites carry a Mobile Communications Subsystem (MCS).
These MCS payloads are leased by INTELSAT to INMARSAT to provide international
mobile satellite services under the label of INTELSAT V MCS.
Radiodetermination. Navigation and Tracking. and Data Relay
Radio location via Loran-C and digital message service is planned by the
GEOSTAR system. Apparently, GEOSTAR will not launch its own satellites, but will
be carried on the yet-to-be-Iaunched SPACENET IIIR and GSTAR III.
A navigation satellite system, called NAVSTAR, is operated by the U.S. Air
Force and provides position location services to the U.S. Government users.
STARFIND is a future system of five, or so, relatively small satellites.
STARFIND will provide radiolocation services.
The Tracking and Data Relay Satellite System (TDRSS) is operated by the
Space Communication Company (SPACECOM) for the National Aeronautics and Space
Administration (NASA). The complete system will comprise two operational
satellites plus an in-orbit spare. In addition to satellite, Shuttle, and
Spacelab tracking support, TDRSS handles high data-rate relays required by space
experiments and other activities.
36
TRANSIT is aU. S. Navy operated satellite system to offer navigation support
for ships at sea.
Experimental Telecommunications
The Advanced Communication Technology Satellite (ACTS) is to be launched
in the early 1990' s. This experimental NASA satellite will operate in the
Ka-band (30/20 GHz). It will feature fixed and movable spot beams, on-board
switching, on-board remodulation, different burst rates, baseband processing,
demand assigned TDMA networking, and associated controls. More about the ACTS
technology and its implications will be presented in subsequent sections of this
report.
Direct Broadcast
The U.S. Direct Broadcast Satellite (DBS) systems appear to be in a state
of inactivity. Around 5 years ago, many companies competed for FCC authorization
to offer video and other direct satellite broadcasts to residences and small user
communities using, where appropriate, the Very Small Aperture Terminal (VSAT)
earth station technology. FCC authorizations were given to four companies: The
Advanced Communications Corporation (ACC); Dominion Video Satellite; Hughes
Communications Galaxy, Inc.; and the United States Satellite Broadcasting Company
(USSB). Several others, such as Direct Broadcast Satellite Corporation (DBSC);
DIRECTSAT Corporation; Continental SatellitE! Corporation; Orbital Broadcasting
Company; and Tempo Satellite, Inc., have either filed for or have received
various design or construction permits. However, at this time due to many
economic reasons, there is no operational DBS in service in the U.S., and none
is expected in the near future.
Weather and Remote Sensing
The National Oceanic and Atmospheric Administration (NOAA) operates two
different weather satellite systems. They are the Geostationary Operational
Environmental Satellite (GOES) system and the Television and Infrared Observation
Satellite (TIROS), which is in polar orbit. The familiar cloud-cover pictures
in television weather broadcasts are typical products of GOES. TIROS data and
photographs are generally used by meteorologists for weather analysis and
forecasting.
37
Multispectral scanning and thermal mapping of the Earth is done by LANDSAT
satellites. LANDSAT is a joint venture by the U.S. Department of Commerce (DOC)
and the U.S. Earth Observation Company (EOSAT).
Earth Observation System (EOS) is run by the EOSAT.
Block SD-2 satellite is formally part of DMSP, but its service is also
available to the civilian community.
Communications Satellites
The geostationary (or FSS) communications satellites represent at least
three stages of implementation. First, there are the operational satellites,
which are in orbit and are ~urrently being actively used. A subclass of these
are ready spares, which are also in GSO, but are kept in reserve to serve as
backup for one or more existing services. Second, there are the FCC authorized
but unlaunched communication satellites. The nearly ready unlaunched or
reserves, which for several reasons happen to be still on the ground, appear to
fall in this category. Finally, the third group consists of so-called planned
satellites. In this case the sponsoring companies or organizations have received
FCC understanding or partial authorization to go ahead with planning, research,
development, partial implemention, and testing on certain subsystems, but they
have not been authorized to launch and operate.
Currently, nine U. S. companies operate domestic FSS satellites. In
alphabetical order they are listed below:
Alascom, Inc. (Wholly owned subsidiary of Pacific Telecom, Inc., which inturn is a wholly owned subsidiary of Pacific Power & Light Co.)
American Telephone and Telegraph Co. (AT&T)
Communications Satellite Corporation (Comsat or Comsat General)
Conte1 Information Systems (Contel ASC)
GE American Communications (GE Americom)
General Telephone and Electronics Corp.· (GTE)
Hughes Communications Galaxy, Inc. (Subsidiary of GM)
MCI Telecommunications Corporation
Satellite Transponder Leasing Corp. (STLC, a subsidiary of IBM).
38
A typical owner/operator from the above list operates one or more GSO
satellites. Table 7 lists 30 operational satellites as cataloged at the end of
1988.
The first column gives the names of the satellites, such as ASC-l, AURORA
I, COMSTAR D2, ... , WESTAR V, in alphabetical order. The second column repeats
the above-mentioned organization that either owns or operates the satellite.
The third column is the year of the launch. The fourth column gives ,in years
the expected useful life for the satellite as planned at the time of the launch.
Some satellites, such as COMSTAR D2, SBS-l, andWestar III, have already exceeded
their initial life expectancy. However, due to the gradual depletion of fuel
and other energy sources, their orbit-keeping and communication roles have
diminished. For present and future planning, these over-aged satellites serve
a limited, perhaps a standby or reserve, role.
The fifth column lists the uplink (earth-to-satellite) and downlink
(satellite-to-earth) transmission frequencies in gigahertz (GHz). For the early
GSO satellites, the common frequencies were in the C-band at 6/4 GHz. The
authorized occupied bands extend from 5.925 to 6.425 GHz on the uplink and from
3.700 to 4.200 GHz on the downlink. Starting with the SBS series in the early
1980's, the 14/12 GHz frequencies in the ~~-band began to be exploited. In the
Ku-band the allowed emissions are between 14.000 and 14.500 GHz on the uplink
and between 11.700 and 12.200 GHz on the downlink.
The sixth column lists the number of channel transponders aboard ·the
spacecraft. Not all of them need be active all the time. Some could be spares
by design, others inactive due to business decisions. The seventh column shows
the channel bandwidths of the transponders in MHz. The existing transponder
bandwidths range from 36 to 72 MHz; however, the majority of the communication
satellites tend to have 24 channels, each with a bandwidth of 36 MHz. A quick
calculation shows that the total bandwidtrL of such 24 channels, including more
than 10 percent guard-bands, must be around 1,000 MHz.
The way that satellite designers fit this 24-channel set into a 500-MHz
allocation is by alternating adjacent-channel polarizations from vertical to
horizontal. Or stated in another way, the guard-space between two channels of
the same polarization is overlapped by the center frequency of the opposite
polarization. Table 8 illustrates this polarization hopping for both uplink and

downlink C-band frequency plans of the Conte I ASC-I satellite. The example is
somewhat atypical, in that it combines 36- and 72-MHz channels. Of course, with
various modulation and multiplexing techniques available today, many analog and
digital signal formats can be carried on these transponders. However, broadband
signals (e.g., the SONET rates) do not fit the satellite channel hierarchies.
Beam coverage is very briefly indicated in column eight. All the domestic
satellites cover the 48 continental adjacent states (CONUS), plus to various
degree, some other areas. These other areas can include Alaska, Hawaii, Puerto
Rico, and adj acent regions near the CONUS. The brief tabulated comment in regard
to the extent of coverage area fails to reflect the fact that the Effective
Isotropic Radiated Power 0EIRP) spatial density varies over the geography of
interest. Figure 8 illustrates a typical C-band EIRP contour over all 50 states.
The satellite in this example is ASC-l, in GSa at 128 0 West Longitude (WL). Note
that the 48-state CONUS can almost everywhere count on an EIRP of 34 dB or
better. However, dependable reception in Alaska is somewhere between 30 and
33 dB, while Hawaii must be satisfied with an EIRP level slightly above 28 dB.
The Ku- band antenna footprints are normally narrower than those of the
C-band. That means that the 14/12 GHz services have potential for more
pronounced EIRP variations over the coverage geography. Figures 9, 10, and 11
depict typical Ku-band EIRP contours of the GSTAR I satellite, parked in orbit
at 103 0 WL. Figure 9 shows the CONUS beam, which implies an EIRP of at least
37 dB for all 48 states. The beam also reveals three regional peaks. The
highest of these is 45 dB, located near St. Louis, MO. Figure 10 shows the
Ku-band east regional beam. In a region between Pittsburgh, PA, and Memphis,
TN, nearly 47 dB may be realized. Finally, the Ku-band west regional beam of
Figure 11 extends from Texas tb the Pacific and from Mexico to Canada. In this
large expanse, it offers an EIRP of at least 40 dB. In some localities, such
as Southern California, Nevada, and Arizona, 45 dB appear possible.
The ninth and final column indicates the types of telecommunication services
provided. Individually, transponders may be dedicated to a specific service
class, such as circuit switched voice (telephony), one of many types of data,
video (TV), private networking, etc. However, given the 36 or more transponders
as a whole, a typical FSS satellite carries a mixture of said services.

As an example, the Telstar satellites of AT&T now offer the tariffed Skynet
,services, individually known as the Skynet Transponder Service, the ,Skynet
Television Service, the Skynet Digital Service, and perhaps several others.
The Skynet Transponder Service provides 36 MHz channels for full-time, large
bandwidth signals, such as rebroadcast television. Full-time transponders can
be leased for periods that are as short. as 1 month or as long as 10 years.
Various degrees of outage and/or preemption protection are available. Partial
and part-time transponder service is also offered, together with different usage
options.
Skynet Television Service carries broadcast-type video plus audio. It is
offered on full- or part-time basis. The service is two-way, but not necessarily
simultaneously. For part-time use, several options are provided for transmit
receive sharing. Dedicated and shared earth-station facilities on customer
premises are offered in such high-usage areas as California, Illinois, and New
York. The Skynet Television Service may be combined wi th the Skynet Transponder
Service to meet the requirements of exceptiotlally large volume customers.
Skynet Digital Service allows any transmit/receive mix of voice, data, and
compressed video, with data rates ranging from 56 k/bs (partial DS-O) to
1.544 M/bs (DS-l), and multiples thereof. Compatible terrestrial interconnect
with the T-carrier is possible at the ACUNET Tl. 5/SKYNET Tl. 5 level. Earth
stations can be dedicated or shared. Service modes can vary from one-way,
two-way, to multipoint broadcasts. The space segment is provided with spare
transponders for outage and preemption protection.
On the future Ku-band satellites, Telstar may offer more advanced services.
An example may be the Skynet Star Network Service. It will implement private,
customer-designed, star-topology networks to provide such services as one-way,
two-way (interactive), and one-to-many broadcast digital data, as well as
broadcast video.
So far only the service menu for the Telstar satellites has been described.
But, all the remaining operational satellites in Table 6 do appear to offer
almost as many and as diverse service options as do the Telstars. To list and
to describe them all here would require too much space in this report.
47
Five organizations have been authorized by the FCC to launch and to operate
additional communication satellites. They are the previously mentioned Contel
ASC, Hughes, GTE, STLC, and a joint venture between~he former RCA (now GE) and
the Horne Box Office (HBO) , called Crimson. Table 9 lists the eight so far
authorized, but not yet launched, U.S. domestic satellites. The column format
in this table is the same as that in Table 6. Note that, except for the
two C-band Hughes satellites and the hybrid C-band plus Ku-band Contel ~SC-2,
the remaining five new satellites are all to be in the Ku-ban4.. lhe beam
coverage areas vary from alISO states to 48-state CONUS, plus regional beams.
The licensed telecommunication services are to be various mixes of voice, data,
television, and provision of private networks.
At least six, and perhaps several more, organizations have additional
systems in various planning or development stages. Generally, these systems have
not yet been authorized by the FCC to either build, launch, or operate. The
companies are Alascom, AT&T, Conte1 , GE Arnericom, Hughes, and the National
Exchange, Inc. All together, they are working on at least 18 satellites.
Table 10 lists these planned, not authorized to either build, launch, or operate,
U.S. domestic FSS satellites. The interesting thing to note about these future
communication satellites is the fact that CONTELSAT-2 proposes to be the first
to venture into the Ka-band, namely at 30/20 GHz, and that SPOTNET-l and
SPOTNET-2 promise to offer spotbeams with transponder bandwidths as high as
167 and 250 MHz.
3.2 ACTS Satellite
The Advanced Communications Satellite (ACTS) is now under development and
scheduled for launch in 1992. It is the main focus of NASA's communications
research and development program. Key ACTS techrlologies include (Wright, 1986;
Jirberg, 1989)
antennas with high-powered electronically hopping multiple beams, plusothers that include a fixed-beam antenna for CONUS-coverage
onboard processing and switching. This boils down to onboard routingof traffic, instead of the traditional fixed "bent pipe" routes throughother satellites
Ka-band transmitters and receivers, instead of C-band or Ku-band

Key ACTS Characteristics
The ACTS antenna beams and their coverage areas are shown in Figure 12.
As a set, these antennas can support at least: several dozen earth stations in
the United States. The hopping spot-beam antennas are polarized either
vertically or horizontally. The fixed spot-beams can be polarized to fit local
and satellite requirements. Two larger scan antennas cover regions denoted as
east and west scan sectors, respectively. Tog,~ther these scan sectors cover the
area from the Eastern seaboard to Chicago, IL. Finally, the steerable antenna
footprint (not explicitly shown in Figure 12) can be used to cover all the
50 states, from Maine to Hawaii and Alaska.
Figure 13 offers a tentative outline of the ACTS communications electronics
package (CEP) onboard the satellite. There are two parallel switches to be
noted: the high burst rate (HBR) microwave switching matrix and the low burst
rate (LBR) baseband processor (BBP). Signals enter and exit these two switches
through common loops of waveguide redundancy switches (also called the three-way
microwave or "baseball" switches). The loops in turn provide direct ports to
the previously discussed satellite antennas. The downconverted IF can be
switched through either switch. The BBP has the capability to act as a
switchboard in the sky, routing individual messages according to the hop cycles
and providing low data rate (such as 64 kb/s) connectivity to end users.
The ACTS radio frequencies are in the Ka-band. That means that the uplink
spectrum is near 30 GHz and the downlink spectrum is near 20 GHz. More
precisely, as illustrated in Figure 14, the uplink spectrum extends from 27.5 to
30.0 GHz. Below the center of the band (the center being defined as 29.420 GHz)

located and 885 MHz wide. It has channel-space for planned ACTS communications
experiments, plus the previously mentioned SMSK modulated data. Briefly, SMSK
is a simplified phase-continuous version of both PSK and MSK. By using
appropriate conversion filters and clock recovery circuits, SMSK is claimed to
save nearly 50 percent of modem implementation costs (Jirberg, 1989). Yet it
yields the same BER performance and a not insignificant improvement in spectral
efficiency.
The downlink spectrum, see Figure 15, is very similar to the uplink
spectrum. The center frequency is shifted down to 19.700 GHz and the HBR band
is reduced slightly to 862 MHz. Downlink telemetry replaces uplink
command/autotrack at the high frequency edge of the band. Fade beacons,
necessary for FEC and channel data rate control, are moved to the other side of
the band.
Data rate control deals with the channel burst rates and the end-user
information rates. Table 11 summarizes their numerical values for the HBR,
LBR-l (wideband) , LBR-2 (narrowband) , and other tentative microwave
transmissions. Note that information rate is specified in megabits per second
(Mb/s) , while depending on binary or quaternary phase modulation, the burst rate
is expressed in mega-symbols per second (Ms/s). For binary modulation the two
measures are indistinguishable. The FEC coding applies only to the LBR mode.
It provides for a 2: 1 reduction in the burst rates and a 4: 1 reduction for
information rates.
ACTS Network Concept
Figure 16 presents a simplified overview of the ACTS network concept. Note
that different user terminals have different burst rate capabilities. The values
shown represent the same modes, plus their more precise numbers, depicted earlier
in Table 11. A very central role is played by the NASA Master Control Station
(MCS). It controls many functions of the ACTS satellite. Included are the tasks
of beam pointingjhopping, FEC and data rate coordination on fading channels, as
well as TDMA traffic management. Traffic management pertains to all LBR and the
HBR stations and terminals who attempt to use the ACTS network.
The following is a brief sketch of the traffic management process. First,
a contending terminal transmits its service request via ACTS to the MCS. Second,
the MCS processes the request and decides on further action, such as either

giving address/routing for permitted calls or service denial for others. Third,
the MCS passes relevant address instructions to the satellite switch, which sets
up the TDMA connection and alerts the terminals involved". During a successful
session, MCS plays a minimal role. However, when the communication session is
over, MCS and the ACTS satellite cooperate in effect by clearing unused channels
and making them available for next would-be users.
The final comment of this section concerns the compatibility of ACTS channel
rates with those employed or planned elsewhere. A quick glance at microwave
system rates (Table 1), existing lightwave hierarchies (Table 2), ISDN data rates
(Table 5), and the recently standardized broaclliand SONET or STS rates (Table 6),
reveals that they have little numerical agreement with the ACTS data rates of
Table 11. If the rates remain as specified now, network interoperation would
require rate conversion interfaces. In real-time operation lower rate channels
must feed into equal or higher rate channels. Even when one is quite careful,
unequal-rate trunking leads to network capacity inefficiencies and associated
economic losses.
3.3 Characteristics and Tradeoffs
As was done earlier in Section 2.4 for terrestrial networks, this section
summarizes the main characteristics, advantages and disadvantages, for the stand
alone satellite networks. As before, the listing is organized according to key
system attributes.
Attribute: Topological Coverage
Advantages Disadvantages
Existing satellite antennas withlarge-area beams provide nationwidebroadcast, or point-to-multipoint,coverage.
New spot-beam antennas are wellsuited for point-to-point services,such as envisioned for VSAT. Spot andfan beams provide frequency reuse,higher EIRP, and given moresophisticated network management, loadshifting and network restoraladvantages.
59
Because of the low satellitebroadcast EIRP, existing earthstations employ large antennas. Suchearth stations are expensive, few innumber, and they require longterrestrial tails (feeder lines) toconnect many sections of the country.
Short terrestrial tails thatavoid all vulnerable parts of theswitched terrestrial network wouldrequire perhaps tens of thousands ofVSAT-like terminals.
-------------_._--_ ..,
The network topologies are veryflexible and adaptive. Terrestrialnodes with existing earth stationscan be added or deleted from thetopology, or their link capacitiesmodified, as quickly as the automatedcontrols will permit.
Attribute: Traffic Capacity
Orbital overcrowding andspectral congestion in tne technicallymatur,e C-band makes one seek differentsatellite solutibns, such as uses ofKu- and Ka-bands (with associated rainoutages), -"smarter" satellites withon-board switching, or limiting theaccess to critical, emergency typeservices.
Advantages Disa~~antages
Today, the total U.S. satellitebandwidth available for communicationstraffic is estimated to be around20 GHz.
The trend toward Ku- andKa-bands, plus satellite technologyadvances, is expected to increase thetotal bandwidth to roughly 50 GHz inthe 1990's.
Satellite traffic can be carriedover a flexible, adaptively changing,network topology. The only constraintis that earth stations must exist atthe network nodes in question.
Increased bandwidth and highergain imply larger capacity trunkingfor Ku- and Ka-bands over the moretraditional C-band.
Attribute: Satellite System Features
The round trip propagation delay(to and from satellite) for aninformation message is approximately1/4 s.
Access control messages that gofrom user to NCC, and back to user,must at least double the delay.
Rain attenuation, especially athigher frequencies, degrades thesatellite link capacity. If weathereffects are severe enough, outages canoccur.
Certain traffic types, such asvoice, CCS, and interactive fast data,can suffer service degradations dueto sat:ellite propagation delays.
Due to orbit and spectrumcongestion, the total U.S. satellitebandwidth is limited to the equivalentof one or two latest generationoptical fibers. Thus, compared to theexisting terrestrial network, thesatellite network has a relativelythin traffic capability.
Advantages Disadvantages
On-board switching of signal, beit at RF, IF, or baseband, can be usedto implement a virtual "digital switch
60
Satellite systems require one ormore network control centers. Theseare Earth-bound facilities that are
in the sky." Automated networkmanagement leads to faster networkrestoral and a more versatile loadshifting.
Switched or hopping satellitebeams are part of a TDMA system thatis controllable, adaptive, and withfast burst rate assignments.
Most, if not all, satellitecarriers offer complete digital andanalog compatibility within theirtransponder bandwidths.
Dual-power or dual-rateoperation, as well as forward errorcorrection can be used effectively forrain-fade compensation.
Phased-array antenna earthstation technology offers flexibledesigns and smaller size elements,which are particularly suited formobile services.
The VSAT systems have a thinroute, direct broadcast, potentialthat seems appropriate for networkrestoral.
Small VSAT terminals offerseveral favorable scales of economy,such as being cheap to manufacture,easy to transport, fast setup, etc.
Attribute: Unique Service Features
subject to all the normal terrestrialvulnerabilities.
Implementation of backup controlcenters may be both a software (i.e.,parallel data processing) and aneconomic burden.
Because of the exposed RF waves,satellite signals are vulnerabfe tohos tile interception, jamming) andmanipulation. Encryption and relatedsecurity measures appear necessary forcontrol and at least for some of theinformation messages.
Other channel interference canbe caused by satellite and terrestrialsystems. The coordination offrequency assignments helps to reduceharmful interference, but one stillfaces a basic limitation on thepermissible number of satellites instationary orbit.
Advantages Disadvantages
Service connectivity to remote,terrestrially not connected, regions.
The siting of earth stationsavoids right-of -way complications andexpenses.
On-demand, high-capacity accessto locations where the economics ofeveryday traffic can justify only athin-route terrestrial linkage.
61
While in orbit, a satellite isnot accessible for technicians torepair or do physical maintenance workassociated with any component failuresor malfunctions.
Satellite failures can be due tomany reasons, hostile or otherwise.Rather typical causes have beenassociated with weakened powersupplies.
Short service life used to be arelative design concern, but thecurrent trends toward quickertechnological turnover everywhere tendto lessen this relative disadvantage.

4. CONCLUSIONS
This report has summarized the present status of stand-alone terrestrial
and satellite networks. It is apparent: that the current primary
telecommunication workhorses are the public terrestrial networks, as they carry
the bulk of the nationwide common carrier traffic. At the same time, the
terrestrial networks and their services have become increasingly vulnerable to
a variety of threats and disasters. Deplorably, these terrestrial network
vulnerabilities appear only to be growing as time passes (National Research
Council, 1989).

Data from 21 ionospheric sounding stations in thenorthern and southern hemispheres were used tocharacterize the day to day variation in the criticalfrequency of the F2 layer of the ionosphere. Variabilityin the critical frequencies are analyzed monthly anddiurnally for quiet magnetic conditions during both lowand high solar periods. In addition, variations in theF2 layer critical frequency are presented for activemagnetic conditions during equinox periods. Tables ofvariabilities for each ten degree increment in magneticlatitude are also provided in this report. Thedependence of variations in the critical frequency withthe solar cycle index IG12 is also discussed.
Key Words: variability, F2 layer, critical frequency, magneticlatitude
1. INTRODUCTION
The F2 region is the most important part of the ionosphere for
propagation of high frequency (HF) signals. The most important F2
layer characteristic is the critical frequency (foF2). Median
values. of this characteristic in part determine the F2 maximum
usable frequency (MUF) for specific distances such that the
probability of HF propagation for this frequency is 50%.
Historically, the frequency that would have a 90% probability of
propagating (FOT) has been assumed to be .85 of the median value of
the MUF and the frequency having a 10% probability (HPF) has been

ionospheric telecommunication circuits relied on manually
constructed contour charts and nomograms to predict the relevant
median ionospheric characteristics. In the early 60' s, the
development of numerical coefficients representing spatial and
temporal variations in the ionosphere, and the availability of
electronic computers made it possible to achieve significantly
greater accuracy in the predictions of circuit performance.
Concurrent with the development of a computer model to predict
the F2 layer MUF, R. M. Davis and N. L. Groome3 examined the
variability in the daily MUF's as a function of all relevant space
and time parameters. The median, upper and lower decile F2 layer
MUF's were computed from the measured foF2 and M(3000)F2 (see
Piggott, 1972, p.15) for 13 U.S. and U.S.-supported vertical
incidence (v.i.) ionosphere stations. A series of local hours in
each month, for three years representing low (1954 or 55), medium
(1961 or 62), and high (1957 or 58) level of solar activity were
used. As ionospheric measurements are now available for at least
two additional solar cycles, it seems appropriate to re-examine
the seasonal, diurnal and latitudinal dependency of the variability
of the daily foF2.
Although Davis and Groome determined the daily variability of
the MUF(3000)F2, Rush et. al. (1974) concluded that the observed
daily variability of foF2 is more important in terms of potential
system degradation than the daily variability of the height of the
maximum (hmF2). Therefore, it was considered efficacious to
analyze only the daily variability of the observed foF2.
In the next section, the selection of the stations and
statistical parameters used in the analysis are described. In the
third section, the observed diurnal, seasonal, solar, magnetic and
latitudinal trends of the statistical parameters are presented. In
Section 4, the relationships between foF2 variability and solar
activity are further discussed. In the last section, the general

2. DESCRIPTION OF THE DATA
The World Data Center A for Solar-Terrestrial Physics has
acquired ionospheric data in digital format from ionospheric
observing stations throughout the world. All ionospheric data
measured at U. S. and U. S. -supported stations have been available in
digital format since the International Geophysical Year (IGY).
More recently, many foreign administrations and organizations have
converted the tabulated ionospheric data from their network of v.i.
stations to digital format. Some of the digital ionospheric data
from non-U.S. v.i. stations have been made available to World Data
Center A. In many cases, though, the data may represent only one
solar cycle, usually solar cycle 21 (1964-76), or only a few years
of this cycle. The main criteria for the selection of data for the
analysis were the total number of years, and more important, the
number of solar cycles for which digital data were available at
World Data Center A for a given station. This eliminated the use
of ionospheric data from many stations.
Initially, the analysis included ionospheric data for six U.S.
or U.S.-supported v.i. stations and seven Australian v.i. stations.
Until recently, none of the ionospheric data for the extensive
Soviet network of v. i. ionosphere stations had been digitized.
These data have been provided to World Data Center A and the
ionospheric data for eight Soviet v.i. stations have been included
in this analysis. The daily variability of the foF2 has been
determined for each hour of every month for all available years for
the 20 v.i. stations listed in Table 1.
In this report, the diurnal variability of the critical
frequency of the F2 layer (foF2) is described for a given month for
v.i. stations at high, mid, and low-latitude ranges. The stations
used to represent these latitude zones are listed in Table 1, along
with their geographic latitude and longitude as well as magnetic
latitude (ML).
Table 1 also includes a list of the years of available data
from each station. As can be seen, data covering two to three

solar cycles were available for most of the stations. studies of
foF2 variability showed that the solar cycle dependency did not
become statistically reliable unless at least two solar cycles (22
years) were included in the analysis.
Data from stations in North America, South America, Asia, and
Australia were utilized, giving a wide range of geographic and
magnetic latitudes in both the northern and southern hemispheres.
The stations were chosen to isolate ionospheric variability effects
that exhibit geographic as well as magnetic dependencies.
comparisons between the foF2 variabilities for stations at
different geographic latitudes and longitudes but similar magnetic
latitudes can highlight the dependency of these variabilities on
geographic and magnetic latitude. Similarly, stations in the
southern hemisphere can be compared to their northern hemisphere
counterparts at the same magnetic latitudes, to determine if
reciprocity with the southern hemisphere exists.
Longitudinal differences in stations may affect variability in
foF2 but are not thoroughly explored in this report because of the
limited longitudinal distribution of the available v.i. stations.
Analysis of the variabilities indi.cated that they are more
dependent upon the latitude range than longitudinal position.
The foF2 data from each station were analyzed for each month
to determine seasonal effects. This report presents the diurnal
variabilities for winter, summer and both equinox seasons. The
diurnal variation in foF2 is summarized in the following sections.
Most of the discussions and analysis in this report are
limited to quiet magnetic periods for both low and high solar
activity years. The ionospherically-derived solar cycle index
termed IG12 is used to characterize the solar cycle dependency of
variability in foF2. Magnetically quiet periods are determined
from the monthly average planetary index for magnetic activity, AP.
Throughout this report, low solar activity periods refer to
occasions where IG12 is less than 41 and high solar activity refers
to periods where IG12 is greater than 109. Quiet magnetic periods
refer to occasions where monthly AP is less than or equal to 15.
The percent standard deviation is calculated for all 24 hours
5
for each month for a given station as follows:
% std dev = (std dev / median foF2) X 100.
The standard deviation is calculated around the monthly median for
each hour in which 10 or more daily values are available. The
median foF2 is the middle value of all ordered foF2 values for a
given hour if the number of observations is odd, and the average of
the two middle values if there is an even number of observations.
All values of foF2 were used to determine the median with the
exception of those values qualified by a D. Qualification by a D
indicates that the actual value of foF2 is greater than the
recorded value. Because of the uncertainty of the measurement,
these values were excluded. The Russian data were checked
separately for the presence of D qualifiers from paper records at
the World Data Center A.
Upper and lower decile factors (see section 3.2) are also
tabulated for each hour of a given month for all stations. Percent
standard deviation has been used in the analysis of variation in
foF2 in order to gain insight into the relative changes in the
ionospheric variability. This is accomplished without having to
account for the differences in the magnitude of the ionization
resulting from solar, diurnal or other changes. Percent standard
deviation is called percent deviation or variability throughout
this report.
3. RESULTS
3.1 Diurnal, Seasonal, and Solar Trends
During the period under consideration in this study--1957 to
1988--there were three solar maxima (1958, 1969 and 1980) and three
minima (1964, 1976 and 85). There were 10 years of low solar
activity (IG12 < 41) and 14 to 16 years of high solar activity
(IG12 > 109) recorded during these years. Table 2 shows the years
included in each month for low, mid and high solar ranges as well
as all magnetic periods.
To characterize the solar activity effects on the foF2 monthly
variability, all variabilities were averaged on an hourly basis for

Diurnal plots of the winter, summer, and spring foF2 variabilities
are given in Figures 1 to 3 for stations representing mid, low and
equatorial latitudes. All percent deviations for low solar and
quiet magnetic periods are included in these figures. The percent
deviations for each hour are averaged and an eight point smoothed
curve (called the characteristic curve) is drawn through the
averages. This characteristic curve allows us to discern large
scale effects in the percent deviation while minimizing
exaggerations in the curve due to extremes in variability that last
only a few hours such as those frequently occurring before sunrise.
A distinct diurnal pattern in the variability is seen in
Figure 1 at Washington and Canberra. The variabilities are
greatest during the night hours when the lowest ionization levels
are observed. The lowest variabilities usually occur between 0800
and 1600 LT. Maui, a low-latitude station, exhibits generally
higher variabilities with the lowest values occurring directly
after sunrise. similar trends are noted at other mid and low
latitude stations (Appendix A) .
Equatorial region variabilities are represented by Huancayo in
Figure 1. At Huancayo the foF2 variability decreases dramatically
directly after sunrise with little day to day variation in foF2
during the remainder of the day. Because of this steep, step-like
decrease in variability, an eight point smoothed curve for this
station seemed inappropriate. Therefore, the actual averaged
values for each hour are used to characterize the variability at
this station.
In contrast to winter, summer variabilities during low solar
periods are generally lower, as shown in Figure 2. The mid
latitude stations show particularly low variabilities with less
extreme diurnal ranges in summer than winter. Maui has 4 to 6
percent lower variabilities from approximately 11-1800 LT during
the summer. The equatorial region variabilities at Huancayo, also
given in Figure 2, show similar trends to winter variabilities with
somewhat higher daylight variabilities. Huancayo is an equatorial
station magnetically but is geographically located at 12 degrees

south and may therefore;exhibit slight seasonal variations with
geographic latitude.
During equinox periods, the mid-latitude stations have almost
negligible diurnal spread in variability as showr. in Figure 3.
Similar to the summer period, the variabilities for mid-latitude
stations range from 12 to 16 percent throughout the day. Maui has
a more extreme diurnal range in variability than the mid-latitude
stations. The lowest daytime variabilities are observed at Maui
during equinox and low solar years. Huancayo has equinox
variabilities that are quite similar to the winter patterns
exhibited in Figure 1.
During low solar periods, the variabilities for mid and low
latitudes are generally inversely related to median foF2. During
the day when critical frequencies increase, variabilities are the
lowest. Likewise at night, when variabillties are highest the foF2
is also the lowest. In summer, less diurnal decrease in foF2 also
correlates with little diurnal change in the variability.
Variabilities for high solar periods are given in Figures 4,
5, and 6 for winter, summer and spring. Again, Washington and
Canberra represent the mid-latitude ranges, Maui the low-latitude,
and Huancayo the equatorial latitudes.
In general, variabilities during periods of high sola~
activity are lower than those shown for periods of low solar
activity. In contrast to low solar periods, the inverse
relationship between the magnitude of the variability and the
median foF2 is less obvious during the spring and summer at mid
latitude stations. During the day, when foF2 is higher,
variability is also higher. Maui has significantly lower
variabilities for all hours during the summer for high solar
periods and an uncharacteristic flat diurnal curve. At Huancayo,
variabilities are generally lower during high solar periods with a
diurnal pattern similar to those noticed during low solar periods.
3.2 Lower Decile, Upper Decile and Standard Deviation
Since the lower bound of the foF2 will in part determine the
frequency likely to propagate for 90 percent of the transmission

period--as will the upper bound determine the 10 percent duration-
the upper and lower decile factors were also analyzed to
characterize the variability in foF2. The decile factor is the
number by which the median is multiplied to obtain the actual 10
and 90 percent deciles for each hour. As with percent deviation,
the decile factors for each hour in a given month were averaged,
then smoothed to obtain the characteristic diurnal curve for both
high and low solar ranges.
Plots of the characteristic curves of upper and lower decile
factors are given in Figure 7 for low solar and quiet magnetic
conditions during winter at washington, Canberra, Maui, and
Huancayo. Also included in this figure are both the upper and
lower standard deviation factors (number by which the median is
multiplied to obtain the actual decile value). Figure 7 shows that
the differences between the lower decile factors and the lower
bound of standard deviation is negligible. Large deviations,
however, can be seen between the upper decile factor and the upper
bound of standard deviation.
Magnetic activity may also affect the variability in foF2.
A'lpert (1973) has shown that during magnetic storms, foF2 tends to
decrease at mid and high-latitudes if the storm commencement is in
the dark hours. Conversely, a positive storm (increase in foF2) is
expected if the storm commences between 0800 and 1300 LT.
Initially, the foF2 increases relative to the median for 2 to 3
hours during the onset, then decreases below the median for a
period which may last as long as 2 to 3 days. Thus the negative
portion (or decreased foF2 phase) of the storm will last longer
when storm activity continues for more than a few hours. For this
reason, the lower decile factor may become depressed as a result of
prolonged magnetic storms.
Since most magnetic activity occurs during the equinox, only
these periods have a sUfficiently large number of high AP's (AP >
19) to study changes in variability with magnetic activity. Figure
8 shows the characteristic curves for high magnetic activity and
high solar periods during the spring equinox at Leningrad, Hobart,
washington and Canberra. These curves show that significant

differences occur between the lower decile and the lower bound of
standard deviation during night hours at high-latitudes. At mid
latitude stations the lower decile is consistently lower than
standard deviation for all hours.
The characteristic curves at all stations during equinox
periods are given in Appendix B for both low and high solar
periods. These plots show the lower decile factor does not deviate
from the standard deviation curve as greatly during low solar
periods.
Negative storms in mid and high-latitudes are accompanied by
positive storms in lower (below ~40 degrees ML) and equatorial
latitudes. The opposite relation is noted for positive storms in
mid-latitudes. As can be seen in Appendix B, variabilities at
lower magnetic latitude stations moderately increase relative to
the median during both low and high solar periods.
3.3 Tabulated Results
A summary of the diurnal variability for each 10 degree
increment in magnetic latitude is given in Table 3 for quiet
magnetic and both low and high solar periods. Characteristic
curves for all stations in each magnetic latitude range are
averaged to produce the values shown in this table. For the
equatorial range (± 5 degrees) Huancayo is the only representative
station. For the 45 to 55 degree N latitude range, however,
characteristic curves for Boulder, Washington, Moscow and
Khabarovsk are all averaged to produce the values listed under this
range. No data were available for the 5-15 or the 25-35 degree
north magnetic latitude ranges. Missing data in mid-latitude
ranges can be interpolated from points in surrounding latitudes.
However the dynamic nature of low-latitude variabilities does not
justify this type of interpolation. Data from the opposite
hemisphere may be used in low-latitude ranges to fill in missing
latitudes for a rough estimate of the variability. Substitution of
southern hemisphere variabilities for northern low-latitudes is not
suggested in practice, but are depicted in Figures 9 and 10 for
reference only.

Figure 10. Latitudinal variabilities for noon (bold) and midnight for quiet magnetic andhigh solar conditions during (a) winter, (b) spring, (c) summer and (d) fall.
Figures 9 and 10 are the noon and midnight variabilities
plotted for each magnetic latitude range for quiet magnetic periods
and low and high solar ranges respectively. In general, high
latitude variabilities are somewhat greater than mid-latitude
variabilities for both noon and midnight during high solar periods,
and at midnight for low solar periods. As noted in section 3.1,
variabilities decrease from low solar to high solar periods. A
symmetry between the northern and southern hemispheres can also be
seen at mid-latitudes in these figures.
At low and equatorial latitudes, variabilities associated with
locations corresponding to the crest of the equatorial anomaly can
be much higher than at mid-latitudes. The equatorial anomaly
occurs in low-latitudes and is centered around the magnetic equator
(Rush et.al., 1969). The anomaly varies in latitude range from
just a few degrees magnetic latitude, to over 20 degrees ML as a
function of solar activity, season, and time of day. Large values
of variability can be seen in low-latitudes at night during low
solar periods. These variabilities may be particularly large
during winter and fall nights for both low and high solar periods.
At noon, slightly higher variabilities can occur around 20 to 30
degrees magnetic latitude during low solar periods. Equatorial
variabilities are generally lower than those noticed at surrounding
latitudes at night.
Tables 'of the diurnal variabilities, upper deciles and lower
deciles for all months and latitude ranges are given in Appendix c.Included in this appendix are the variabilities for low (IG12 5
40), medium (40 < IG12 > 110) and high (IG12 ~ 110) solar ranges.
Variabilities for the middle solar ranges are included in this
appendix. During certain periods, a straight line interpolation
from low to high solar periods does not sUfficiently represent the
variabilities calculated from the data. Because of the general
increase in magnetic activity during equinox periods, Appendix C
also contains variabilities for active magnetic periods (AP > 19)
in March, April, September, and October. Also because of an
increase in the level of magnetic activity during equinox periods,
AP less than 20 is more representative of the average level of
30
activity. Therefore, variabilities were also calculated for AP
less than 20 for the equinox periods and are also included in
Appendix C.
4. REGRESSION
The plots summarized in Section 3 indicate a solar cycle
dependency of the variability. This dependency is further examined
by calculating the first order regression of variability with IG12.
The slope of the regression line is given in Table 4 for each hour
and month for all stations. Only magnetically quiet variabilities
were included in the slopes of the regression lines given in Table
4. The hours where the gradient of the regression lines were
deemed to be significant (3 percent or larger) are underlined in
this table, and the negative slopes are highlighted with a dot.
Table 4 shows that many of the highlighted slopes are
negative, indicating a decrease in variability with increasing
solar activity. For the mid to high-latitude stations, a negative
correlation with solar activity occurs during summer night and
winter early evening and late morning hours. positive correlations
with IG12 occur mainly during summer daylight hours. In the
southern hemisphere, where the seasons are reversed~, the patterns
exhibited in this table are also reversed.
Variabilities at low-latitudes are more dependent on solar
cycle than high-latitude stations. At Maui, Concepcion, and Vanimo
more then 70 percent of the hours show significant negative solar
cycle dependency. At the magnetic equator, Huancayo shows mostly
negative solar cycle dependency between 2300 and 0700 LT.
Although the regression coefficients for the slopes summarized
in Table 4 do not always indicate significance, the patterns that
are shown are quite consistent. The low-latitude stations--Maui,
Vanimo, and Concepcion--show the greatest solar cycle dependency in
variability. In general, the mid-latitude stations show somewhat
less solar cycle dependency than low-latitude stations, however,
the patterns illustrating which hours and months have positive and
negative solar dependencies are consistent among these stations.
A few examples of the regression lines are shown in Figures 11
31

and 12. Noon and midnight variabilities are plotted against IG12
during the month of April for Tomsk, Boulder, Maui and Brisbane.
Although variabilitiesfpr all years are shown on these plots, the
regression line shown is calculated including only magnetically
quiet data points (indicated by a plus in the figures).
As can be seen in these figures, most of the variabilities
associated with high AP (AP > 19, and indicated by an 0 in the
figures) are higher than the regression line at both noon and
midnight at Boulder and Tomsk. At ~1aui and Brisbane however, the
magnetically active variabilities do not deviate as drastically
from the quiet variability regression line. Since Maui is a low
latitude station, and Brisbane is more than 12 degrees ML lower
than either Boulder or Tomsk, magnetic activity may have less
effect on variability at lower latitudes.
5. SUMMARY
This report characterizes the variability in the F2 layer
critical frequency of the ionospherE~. Based on initial studies of
the variability, foF2 is characterized on a seasonal, solar and
diurnal basis for magnetically inactive periods. Upper and lower
deciles of foF2 were also determined for purposes of comparison to
the standard deviation factor. The difference between the decile
factors and the standard deviation factor is negligible when
magnetic activity is not considered.
Magnetic activity, however, will affect the variability in
foF2. Due to the complicated nature of the interaction of magnetic
activity with foF2, magnetic influences were not investigated
extensively in this report. Examples of variability for
magnetically active conditions during equinox periods are, however,
given in this report. These examples show that during magnetically
active, high solar periods, the lower decile of the foF2 may become
depressed. Low solar and active magnetic periods do not show this
depression in the lower decile factor, though marked deviations
between the upper decile and standard deviation are noticed.
For most communications applications, the frequency which will
propagate for 90 percent of the transmission period is required.

The distribution of the foF2 will limit this frequency as will the
lower decile of the 3000 km transmission factor (M(3000)F2). In
magnetically active periods, it may be better to use the lower
decile factor. During quiet magnetic periods, the difference
between the lower decile and standard deviation characterizations

propagate 90 percent of time.
For prediction purposes, the tables presented in section 3.3
and Appendix C, can easily be incorporated into a computerized
format to enhance the prediction of F2 layer parameters. Given a
monthly median foF2, these tables could then be used to describe
the distribution of the daily foF2's around the median for high,
medium and low solar activity as well as for active magnetic
equinox periods.
of
Although this report summarizes the daily variation in foF2
for quiet periods and certain active magnetic periods, extreme
variations in foF2 may occur during magnetic storms. Because of
the complicated nature of the interactions between foF2 and
magnetic activity, a description of this phenomenon requires more
detailed study.

15. ABSTRACT (A 200-word or less factual summary of most significant information. ,II document includes a significant bibliography or literaturesurvey, mention it here.)
Data from 21 ionospheric sounding stations in the northern andsouthern hemispheres were used to characterize the day-to-day variationin the critical frequency of the F2 layer of the ionosphere.Variability in the critical frequencies are analyzed monthly and diurnallyfor quiet magnetic conditions during both low and high solar periods. Inadditi on, variations in the F2 layer critical frequency are presented foractive magnetic conditions during equinox periods. Tables of variabilitiesfor each ten degree increment in magnetic latitude are also provided in thisreport. The dependence of variations in the critical frequency with thesolor cycle index IG12 is also discussed.
